The model utility content
The utility model technical problem to be solved provides a kind of leather bucket formula pipeline that is applicable to high pressure sewage type operating mode from force control valve.
In order to solve the problems of the technologies described above; The leather bucket formula pipeline that the utility model provides is from force control valve; Comprise valve body, outlet end by-pass line, piston rod, piston cylinder, entrance point by-pass line, eccentric big valve plate, valve shaft, connecting rod, bearing pin and little valve plate; Two leather cup pressing plates are clamped two leather cups installing back-to-back up and down; The end that described leather cup and described leather cup pressing plate adopt nut to be installed in and be in the described piston rod in the described piston cylinder forms piston, and described outlet end by-pass line is communicated with the rodless cavity of described piston cylinder, and described entrance point by-pass line is communicated with the rod chamber of described piston cylinder.
Described leather cup is the molded and middle nylon strengthening net muscle that is provided with by rubber pattern, and the leather cup edge is protruding, and the center is provided with circular hole, and its size and piston rod are measure-alike, so that piston rod passes, and being connected and sealing through the realization of leather cup pressing plate and piston rod.
One end of described connecting rod is articulated on the described valve shaft and can rotates around the center of described valve shaft; The other end of described connecting rod and described little valve plate fuse; Described connecting rod middle part is provided with slotted hole; Bearing pin is free to slide and interts in described slotted hole, and the lower end of described piston rod is connected with described bearing pin.
Described connecting rod is as a whole through welding, casting or forge into described little valve plate.
The leather bucket formula pipeline that adopts technique scheme is from force control valve, leather cup formula piston by two leather cups installing back-to-back and up and down two leather cup pressing plates form, be connected with piston rod through nut.Leather cup is molded by rubber pattern, and the centre is provided with nylon strengthening net muscle, to improve the leather cup compressive strength; The leather cup edge is protruding, so that better strike off the dirt on the piston in cylinder wall; The leather cup center is provided with circular hole, and its size and piston rod are measure-alike, so that piston rod passes, and realizes and being connected and sealing of piston rod through the leather cup pressing plate.Because leather cup has better elastic, its convex edge can and the inwall of piston cylinder between produce suitable pretightening force; First, can realize the sealing of leather cup formula piston (leather cup pressing plate+leather cup) upper and lower cavity; Second, when leather cup moves up and down, can strike off the sediments on the piston cylinder inwall automatically, prevent fouling.Valve is not if having an open and close for a long time, may fouling on the inwall of piston cylinder, because leather cup has better elastic, still can pass through, and the phenomenon that steel piston blocks easily can not appear.Because the leather cup pressing plate is made with steel, can bear elevated pressures, therefore, leather cup formula piston (leather cup pressing plate+leather cup) is applicable to high pressure (below the 10.0Mpa) sewage medium.
In sum, the utility model is a kind of advantage that combines diaphragm type and piston cylinder operator, applicable to the leather bucket formula pipeline of high pressure sewage type operating mode from force control valve.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Referring to Fig. 1; Outlet end by-pass line 2, piston rod 5, piston cylinder 9, bolt 3, cylinder cap 4, entrance point by-pass line 10, eccentric big valve plate 11, valve shaft 12, connecting rod 13, bearing pin 14 and little valve plate 15 are installed on the valve body 1; Bottom at the big valve plate 11 of off-centre is provided with discharge orifice 16; Two leather cup pressing plates 7 are clamped two leather cups 8 installing back-to-back up and down, and leather cup 8 is the molded and middle nylon strengthening net muscle that is provided with by rubber pattern, and leather cup 8 is installed in the end that is in the piston rod 5 in the piston cylinder 9 with leather cup pressing plate 7 employing nuts 6 and forms piston; Outlet end by-pass line 2 is communicated with the rodless cavity of piston cylinder 9, and entrance point by-pass line 10 is communicated with the rod chamber of piston cylinder 9.One end of connecting rod 13 is articulated on the valve shaft 12 and can rotates around the center of valve shaft 12; The other end of connecting rod 13 is through welding, casting or forging and little valve plate 15 integral body that fuses; Connecting rod 13 middle parts are provided with slotted hole 17; Bearing pin 14 is free to slide and interts in slotted hole 17, and the lower end of piston rod 5 is connected with bearing pin 14.
Referring to Fig. 1, leather cup formula piston by two leather cups 8 installing back-to-back and up and down two leather cup pressing plates 7 form, be connected with piston rod 5 through nut 6.Leather cup is molded by rubber pattern, and the centre is provided with nylon strengthening net muscle, to improve the leather cup compressive strength; The leather cup edge is protruding, so that better strike off the dirt on the piston in cylinder wall; The leather cup center is provided with circular hole, and its size and piston rod 5 are measure-alike, so that piston rod 5 passes, and realizes and being connected and sealing of piston rod 5 through leather cup pressing plate 7; Because leather cup 8 has better elastic, its convex edge can and the inwall of piston cylinder 9 between produce suitable pretightening force; First, can realize the sealing of leather cup formula piston (leather cup pressing plate 7+ leather cup 8) upper and lower cavity; Second, when leather cup 8 moves up and down, can strike off the sediments on piston cylinder 9 inwalls automatically, prevent fouling.Valve is not if having an open and close for a long time, may fouling on the inwall of piston cylinder 9, because leather cup has better elastic, still can pass through, and the phenomenon that steel piston blocks easily can not appear.Because leather cup pressing plate 7 usefulness steel are made, and can bear elevated pressures, therefore, leather cup formula piston (leather cup pressing plate 7+ leather cup 8) is applicable to high pressure (below the 10.0Mpa) sewage medium.
The working principle of the utility model:
Drive valve: referring to Fig. 1 and Fig. 2; Work as starting mode of pump; The entrance point water flow pressure of valve body 1 raises and during greater than the outlet end pressure of valve body 1 gradually, and a part of current get into the cavity of resorption of piston cylinders 9 along entrance point import by-pass line 10, promote leather cup formula piston (leather cup pressing plate 7+ leather cup 8) and drive piston rod 5 slowly up; Mention little valve plate 15, remove constraint the big valve plate 11 of off-centre; Simultaneously, the current of piston cylinder 9 epicoeles are entered the outlet end of valve body 1 through outlet end by-pass line 2; At this moment, eccentric big valve plate 11 follows little valve plate 15 closely and rotates around valve shaft 12 clockwise directions under the promotion of current, and valve is slowly opened.
Close valve: referring to Fig. 3 and Li Xin, during termination of pumping, water velocity plunges in the valve, and the gravitational moment that eccentric big valve plate 11 utilizes eccentric structure to produce is closed rapidly, and most current in the block valve have only discharge orifice 16 that a small amount of backflow is arranged; At this moment; Because the outlet end pressure of valve body 1 is greater than the entrance point pressure of valve body 1; The outlet end current of valve body 1 get into the epicoele of piston cylinder 9 along outlet end by-pass line 2; Promote leather cup formula piston (leather cup pressing plate 7+ leather cup 8) and drive piston rod 5 slowly descending, force little valve plate 15 counterclockwise to rotate, slowly close discharge orifice 16 around bearing pin 14; Simultaneously, the current with piston cylinder 9 cavity of resorptions enter the valve body entrance point through entrance point by-pass line 10.
